Multi Compartment Container Cap

ABSTRACT

A multi-compartment container cap comprising a hollow tubular body having a dividing wall forming a proximal compartment located at a proximal end of the hollow tubular body and a distal compartment located at the distal end of the hollow tubular body. The proximal end of the hollow tubular body is adapted to be releasably attached to a container body while the distal compartment comprises a separate compartment for the storage and dispensing of a composition which can be selected to be complementary to any composition store within the container cap.

FIELD OF THE INVENTION

The present invention relates generally to the field of removable caps for bottles and containers. More specifically, the present invention relates to a convenient and easy to use article which allows two or more products to be stored in the same container in separate compartments.

BACKGROUND OF THE INVENTION

Container caps having more than one function are known. For example, many container caps provided on conventional laundry detergent bottles provide the dual functions of releasably sealing the container and providing a dosing feature to allow consumers to measure a predetermined volume of the laundry detergent composition for use. Dosing caps are commercially available in a variety of products, including in containers for liquid or granular laundry detergents and fabric softeners. Examples of dosing caps are available in U.S. Pat. No. 2,985,343 to Mask; U.S. Pat. No. 4,892,126 to Bucherer et al.; U.S. Pat. No. 5,662,249 to Grosse; U.S. Pat. No. 5,855,302 to Fisscher et al.; U.S. Pat. No. 5,865,331 to Jacobs et al.; U.S. Pat. No. 6,422,426 to Robins, III et al.; and U.S. Patent Publ. No. 2001/0030165 A1 to Jacobs et al.

In addition, multi-compartment containers are known. See, e.g., U.S. Pat. No. 2,899,096 to Henchert et al. These multi-compartment containers have many different purported uses. One category of multi-compartment containers uses the separate compartments to keep different component ingredients separate during storage but allows for mixing prior to use. Examples of these multi-compartment containers are described in U.S. Pat. No. 5,255,812 to Hsu et al.; and U.S. Pat. No. 5,954,213 to Gerhart et al. Another category of multi-compartment containers are designed to provide a composition reservoir in a first compartment and a composition dispensing mechanism in a second compartment. The composition dispensing mechanism extracts the composition from the first compartment and dispenses the extracted composition. Examples of these types of multi-compartment containers are described in U.S. Pat. No. 2,553,302 to Keskitalo; U.S. Pat. No. 4,636,328 to Flynn et al.; U.S. Pat. No. 5,188,472 to Sgro; and U.S. Pat. No. 7,066,674 to Gueret.

Although container designers and manufacturers have reported many different types of dosing caps and multi-compartment containers, there remains a need for a container cap which can provide the multiple functions of conventional container caps, as well as creating a multi-compartment container for storing and /or packaging a complementary product. The complementary product can be used with the composition stored within the container or can be used in a stand alone application. As such, there remains a need for a new container cap which provides the functionality of a conventional container cap, such as protecting the contents of the container from undesired exposure to the environment and dosing, while providing multi-compartment storage capabilities. Further, the new container cap should be user friendly and simple to manufacture.

DETAILED DESCRIPTION OF THE INVENTION Definitions:

As defined herein, hermetic refer to seals between container components (such as the lid and multi-compartment container cap and the multi-compartment container cap and container body) which provide at least a degree of resistance to moisture migration through the seal, at least equal to that of the container and hollow tubular body materials. Such seals may also provide resistance to migration of gases at least equal to that of the container body and lid materials

As defined herein, hollow tubular body means a conical, cylindrical, squared or other multi-sided shape which can have the same or varying shape and/or cross sectional area along its height. Non-limiting examples of suitable container cap shapes are provided in U.S. Pat. Nos. D390,466 and D390,462 both to Mao; U.S. Pat. No. D389,740 to Toleman; U.S. Pat. No. D189,059 to Vanderhyde; and U.S. Pat. No. D306,265 to Jeo.

As defined herein, substantially perpendicular to a planar surface means that upon determining a normal vector to said planar surface, any line intersecting said planar surface forms an angle of between about 0° and about 15° from said normal vector. Where the surface does not form a plane, the normal vector is determined by ascertaining the center point of said surface, then taking the normal vector of the tangential plane to the center point of said surface.

As defined herein, substantially water tight means that no appreciable amount of liquid water will is visibly observed to pass through a sealed compartment under ambient environmental conditions.

FIG. 1 illustrates a container body 600 with a multi-compartment container cap 100 in accordance with at least one embodiment of the present invention. Container body 600 comprises a reservoir 640 capable of storing a liquid or granular composition, and a neck 620 adapted to be removably attached with a corresponding container cap. FIG. 1 shows a cut away 650 revealing the interior contents of the reservoir 640. Granular or liquid composition 700 is shown stored within reservoir 640. Any container body which can be closed with a container cap can be used with the present invention. In one embodiment, the container body has a separate handle, not shown, such as available with commercially marketed laundry softener or detergent containers and automatic dish washing gel or liquid containers. Those of skill in the art will understand that container bodies without handles are also within the scope of the present invention. Non-limiting examples of container bodies which can be used in accordance with the present invention include containers for liquid or granular laundry detergents, liquid fabric softeners, paint containers, bottles for liquid or granular hard surface containers, aerosol cans, food containers such as cookie jars, beauty and cosmetic containers, and so forth.

The container cap shown in FIG. 1 is a multi-compartment container cap 100 having a hollow tubular body 110 comprising a proximal end 200 and a distal end 300. Within said hollow tubular body is a dividing wall 150 separating said hollow tubular body into a proximal compartment 210 and a distal compartment 310. Those of skill in the art will understand that the dividing wall 150 can be a single layer wall or a dual or multi layered wall. When said multi-compartment container cap 100 is removably attached to said container body about said neck 620, a substantially water tight seal is created. In one embodiment, this substantially water tight seal between said multi-compartment container cap 100 and the container body 600 is a hermetic seal (not shown).

FIG. 2 is a cross section view of the multi-compartment container cap 100 shown in FIG. 1, taken along view lines A-A. Any conventional container body which is suitable for storing compositions including but not limited to liquid, granular, gelled and semi-solid compositions can be used in accordance with the present invention, including but not limited to container bodies for storing liquid laundry detergent or fabric softener. In addition, the container body can be an aerosol can, a spray bottle for hard surface cleaning compositions, and any container body which is used suitable for storing a composition and adapted to be closed with a removable cap.

The multi-compartment container cap 100 comprises a hollow tubular body 110 forming a proximal end 200 and a distal end 300. The portion of the hollow tubular body forming said proximal end further comprises a container attachment member 255 adapted to form a substantially water tight removable closure with the neck of a container. The multi-compartment container cap further comprises an axial dimension 160 extending through the length of said hollow tubular body; and a dividing wall 150 separating said hollow tubular body into a proximal compartment 210 and a distal compartment 310. The axial dimension 160 intersects the dividing wall 150 in a transverse orientation. In one embodiment, the dividing wall 150 is a planar surface. In another embodiment, the dividing wall is a cupped surface, wherein the cupped surface can be concave towards the proximal end or convex from the proximal end, or an otherwise non-flat surface which can contain flat portions, convex portions and concave portions. In one embodiment, the axial dimension is substantially perpendicular to said dividing wall, alternatively perpendicular to said dividing wall. The portion of the tubular body 110 forming the proximal compartment 210 forms a proximal opening 220 at the proximal end 200. The portion of the tubular body 110 forming the distal compartment 310 forms a distal opening 320 at the distal end 300. In one embodiment, the distal opening comprises a distal opening comprises an opening size of from about 5 cm² to about 200 cm², alternatively from about 20 cm² to about 150 cm², alternatively from about 50 cm² to about 100 cm²

As shown in FIG. 2, in one embodiment, the distal compartment 310 contains a pouched article 500. Those of skill in the art will understand that the composition contained within the distal compartment can be chosen to be complementary to the composition stored within the container body. For example, where the composition stored in the container body is a liquid, gel, or granular detergent composition, the composition stored in the distal compartment can be complementary to the composition stored in the container body. As defined herein, “complementary” means combination of products which can be used together in parallel, or used in a series of steps; or used in separate but related steps such as where the container body contains a liquid or gelled automatic dish washing composition and the composition stored within the distal compartment is a wet nap for treating hard surfaces. Those of skill in the art will understand that any two or more products which can be suitably marketed together can be contained by a container and cap in accordance with at least one embodiment of the present invention.

In one embodiment, the composition contained within the container body, as shown in FIG. 1, is a liquid, gel or granular laundry or hard surface detergent composition, such as an automatic dish washing composition or a car washing formulation. In another embodiment, the composition stored within the distal compartment of the container cap is a granule, a sheet, a pouch or a tabletted treatment composition which can be used in a laundry application. Non-limiting examples of compositions which can be placed within the distal compartment include: one or more softening and/or antistatic dryer sheets; one or more whitening or bleaching tablets comprising additional surfactants, bleaches, bleach activators and mixtures thereof; one or more pouched odor controlling agent such as a perfume additive comprising free perfume, encapsulated perfumes, cyclodextrin compositions, malodor control agents, and mixtures thereof; and combinations thereof. This is believed to be particularly useful in situations where the manufacturer wants to provide consumers with a sample product which is complementary to any product marketed within the container body. For example, in one embodiment, TIDE® liquid laundry detergent is stored within the container body and a BOUNCE® dryer sheet is provided within the distal compartment of the multi-compartment container cap. The two products can be complementary in terms of the desired end use and/or they can include complementary elements such as the same or a similar fragrance scent; the same or a similar perfume ingredient; the same or similar aesthetic appearance such as coloring or pearlescence; and combinations thereof. In another embodiment, the products marketed within the container body and the multi-compartment container cap are chosen to provide a synergistic benefit when used in parallel or in series. Those of skill in the art will understand that combinations of products can be used to provide a desired end user benefit such as overall scent experience, stain repellency, shine on hard surfaces, etc. In one embodiment, the container body and/or the distal compartment is empty such that a consumer can fill either compartment with any combination of objects or products they desire.

FIG. 2 further shows a multi-compartment container cap comprises a lid 400, which is in a detached position. The lid can form a substantially water tight removable closure when sealed onto said distal end 300, thereby removably sealing said distal compartment 310. In one embodiment, the multi-compartment container cap, or any portion thereof can be translucent or transparent such that a consumer can see the interior contents. In one embodiment, the lid 400 is translucent or transparent. In another embodiment, the hollow-tubular body or a portion thereof is translucent or transparent.

FIG. 3 illustrates the upper portion of another opened container body 600 with a corresponding multi-compartment container cap 100 in accordance with at least one embodiment of the present invention. Partial cut-away 312 reveals that a granular composition 505 is located within the proximal compartment 310. Further, in this embodiment, the multi-compartment container cap 100 is shown with the lid 400 removably attached upon the proximal opening. The lid shown in this embodiment comprises a plurality of ribs 410 adapted to allow a user to grip and turn the lid to remove it from the hollow tubular body 110.

FIG. 4 illustrates a multi-compartment container cap 100 in accordance with at least one embodiment of the present invention. The multi-compartment container cap shown in FIG. 4 is in an inverted position such that the proximal end 200 of said hollow tubular body 110 is in an upwards orientation such that a measured volume of liquid, gel, or granular composition 610 is collected in said proximal compartment of the multi-compartment container cap.

A dosing indicator 230 is provided on said hollow body 110 to allow the end user to determine the amount of composition which can be dosed into the proximal compartment. The dosing indicator shown in FIG. 4 is a visual indicator in the form of a fill line comprising a groove formed in at least a portion of the interior of the proximal compartment. Those of skill in the art will understand that one or more dosing indicators can be provided on the interior of the proximal compartment, for example where the composition stored within the container body is a fabric softener, the dosing indicator can include a first fill line for “Soft” a second fill line for “Extra Soft.” Those of skill in the art will also understand that the dosing line can be positioned to allow the user to measure a predetermine amount of the composition depending upon the recommended dosage amount, for example from about 0.5 fl. oz. to about 5 fl. oz., alternatively from about 1 fl. oz. to about 3 fl. oz. In one embodiment, the dosing indicator comprises more than one fill line. In another embodiment, the dosing indicator comprises an indicia applied to the surface of the interior of the proximal compartment, such as ink or paint indicia; physical deformations to a portion of the interior of the proximal compartment, including protuberances and/or grooves applied to the interior of the proximal compartment; and combinations thereof. The dosing indicator can be applied to a portion of a ring around the interior of the proximal compartment, applied to a full ring around the interior of the proximal compartment, or combinations thereof.

A partial cut away 312 reveals a pouched article 500 contained within the distal compartment. The multi-compartment container cap of FIG. 4 is shown with the lid 400 in a detached position. In this embodiment, although the lid is not attached to the distal opening 300, the composition stored within the distal compartment will not necessary fall out when the multi-compartment container cap is in an orientation where the distal end is facing downwards and the lid is not attached. In one embodiment, a removable freshness seal is provided (not shown in this embodiment) further sealing said distal opening 300. In one embodiment, the removable freshness seal is a foil wrapper which restricts or prevents air from passing into the distal compartment. In one embodiment, the removable freshness seal hermetically seals the interior of the distal compartment from the ambient environment.

In one embodiment, the composition contained within the distal compartment comprises: a granular composition, a pouched article, a substrate, tabletted products, such as molded products like vitamins or laundry/dish washing detergent tablets; and combinations thereof. In one embodiment, the distal compartment contains one or more compositions wherein the compositions can be the same form having the same or different variants (such as a plurality of pouched articles with varying scents or colors) or have the same form and be the same variant. In one embodiment, where the distal compartment comprises a pouched article, the pouched article comprises a water-soluble or partially soluble film material such as polyvinyl alcohol or a derivative thereof. In another embodiment, the pouched article comprises a single compartment pouch, a dual compartment pouch, or a multi-compartment pouch, wherein said pouched articles are adapted to store a liquid composition, a granular composition, a gelled composition, and mixtures or combinations thereof. Examples of suitable pouched articles and suitable water-soluble films for use therein are provided in U.S. patent application Ser. No. U.S. Pat. No. 6,881,713 to Sommerville-Roberts et al., U.S. Pat. No. 6,815,410 to Boutique et al., and U.S. Pat. No. 7,125,828 to Catlin et al. Where the composition contained within the distal compartment is a substrate, the substrate can be in the form of folded sheets or a roll of sheets as shown in FIG. 16.

FIG. 5 illustrates another multi-compartment container cap in accordance with at least one embodiment of the present invention. Those of skill in the art will recognize that the lid 400 of FIG. 5 is adapted to form a removable seal with said distal compartment 310 at the distal opening 320. In one embodiment, the lid forms a substantially water tight seal with said distal opening 320. The lid of FIG. 5 comprises one or more attachment members 455 which are adapted to fit with one or more receiving members 355 from said distal compartment. In one embodiment, said one or more attachment members are designed such that the lid is a screw-on lid, such as a partial turn lid, a quarter turn or half turn lid. In another embodiment, the attachment members of the lid are a full thread such that the lid is a screw-on lid which can require one or more full revolutions. In another embodiment, the lid is a snap on lid, where said one or more attachment members of said lid and said receiving members of said hollow body 110 can be either ball and socket or tongue and groove fitments such that the lid can be snapped onto the hollow body to form a closure around the distal opening. In another embodiment, the lid comprises both screw-on and snap-on receiving members. Those of skill in the art will understand that the container attachment member 255 can similarly be selected such that the multi-compartment container cap is either a screw-on cap, a snap-on cap, or a combination thereof.

In the embodiment illustrated in FIG. 5, the lid 400 comprises a gripping member 410 formed on the outer surface of the lid. In one embodiment, the gripping member is selected from the group consisting of one or more vertical ribs; one or more horizontal ribs, and combinations thereof.

FIG. 6 illustrates a top view of the lid 400 shown in FIG. 5. As shown in this figure, the gripping member 400 includes both a plurality of vertical ribs 411 and a horizontal rib 412. Those of skill will understand that vertical ribs are particularly useful for screw-on lids, whereas horizontal ribs are particularly useful for snap-on lids.

FIG. 7 illustrates a side view of the multi-compartment container cap 100 with the lid 400 removably attached onto the distal opening.

FIG. 8 illustrates a side view of the multi-compartment container cap 100 shown in FIG. 5 with dashed lines showing some interior features of said multi-compartment container cap. A dividing wall 150 is provided to separate said hollow tubular body into a proximal compartment 210 and a distal compartment 310.

FIG. 9 illustrates an elevated side view of a multi-compartment container cap 100 in accordance with another embodiment of the present invention. The lid 401 comprises a hinged flip top lid wherein the surface of said flip top lid forms an opening which is hingedly closable from a hinged flap 420 which can be swung open to reveal the interior contents of the distal compartment. Those of skill in the art will understand that the amount of the lid surface which is occupied by said flip top opening can be varied based on the desired access area desired. In one embodiment the lid 400 forms an access area of from about 10% to about 80% of the planar area of said lid; alternatively from about 30% to about 70%, alternatively from about 40% to about 60%. As defined herein, the lid area means the planar area occupied by the outer perimeter of the lid of the present invention if the outer perimeter were superimposed on a flat surface.

FIG. 10 illustrates another elevated side view of the multi-compartment container cap 100 shown in FIG. 9. In this view, the hinged flip top lid 401 is removed from the multi-compartment container cap, revealing the dividing wall 150. The hinged flip top lid can also be a screw-on lid and/or a snap-fit lid to allow the hinged flip top lid to form a removable seal with said hollow tubular body 110 at the location of the distal opening.

FIG. 11 illustrates a side view of the multi-compartment container cap 100 shown in FIG. 9. The hinged flap 420 is in a partially open position.

FIG. 12 illustrates a side view of the multi-compartment container cap 100 shown in FIG. 9 with dashed lines showing some interior features of said multi-compartment container cap. Dividing wall 150 separates the hollow tubular body 110 into the proximal compartment 210 and the distal compartment 310.

FIG. 13 illustrates an elevated side view of a multi-compartment container cap 110 in accordance with yet another embodiment of the present invention. FIG. 13 shows an embodiment of the present invention wherein at least one of said lid 402 and said hollow tubular body 110 forming said distal compartment comprises a minor distal opening 430. Lid 402 comprises at least one minor distal opening 430 providing an access path from the interior of the distal compartment to the environment external to the multi-compartment container cap. In addition, the hollow tubular body 110 forms another minor distal opening 330. Said one or more minor distal openings are adapted to allow a composition to be transferred from the distal chamber to the exterior of the multi-compartment container cap. The composition which is transferred can be a substrate or granular composition which can be released like salt from a salt shaker. In one embodiment, the minor distal opening comprises an opening size of from about 0.01 cm² to about 5 cm², alternatively from about 0.03 cm² to about 4 cm², alternatively from about 1 cm² to about 3 cm². In one embodiment, said minor distal opening is formed in a shape which facilitates the separation of sheets which can be in a roll contained within the distal compartment. In one embodiment, the shape of the minor distal opening is selected from the group consisting of: a tapered opening which is can be triangular or isosceles trapezoid; a rectangular opening; an X shape; a circle; or square. In another embodiment, the shape is tapered such that the cross section area of the minor distal opening facing the interior of the distal compartment is smaller than the cross sectional area of the opening facing the exterior of the multi-compartment container cap. These and other shapes which facilitate the distribution and tearing of substrates which can be in a roll with tear lines separating individual doses of the substrates are within the scope of the present invention.

FIG. 14 illustrates another elevated side view of the multi-compartment container cap 100. Lid 402 comprises a minor distal opening which comprises an obstructing member 435. In one embodiment, the obstructing member comprises a flexible membrane disposed over said minor distal opening, said flexible membrane having at least one aperture or cut in the membrane to allow a substrate to be drawn out of the distal compartment. In one embodiment, the flexible membrane comprises a silicone rubber membrane. Non-limiting examples of flexible membranes which can be used in accordance with the present invention are disclosed in U.S. Pat. No. 5,989,469 to Dirr et al., U.S. Pat. No. 5,931,352 to Dirr et al., U.S. Pat. No. 5,897,033 to Hiroyuki Okawa et al., U.S. Pat. No. 4,728,006 to Drobish et al. Other obstructing members can be a hook or tooth which is extends into the center of the minor distal opening such that the obstructing member can catch any separation between passing sheets and allow the sheets to separate upon a user pulling on a dispensed sheet.

Those of ordinary skill will understand that any obstruction or flexible membranes which can allow a substrate to be drawn out of the interior of the distal compartment can be used with the minor distal opening in order to provide an obstruction to assist in separating any substrates within the distal compartment or to control the amount of any granular composition poured out of the distal compartment. As mentioned herein, the minor distal opening can be located on the lid as shown as 430 or on a portion of the hollow tubular body forming the distal opening as shown as 330. As shown in FIG. 13, the minor distal opening 430 can be shaped to act as an obstructing member where the edges of the minor distal opening can catch a portion of the substrate allowing a user to pull on the substrate dispensed through the minor distal opening and separate said dispensed substrate from any other substrates within the distal compartment.

The multi-compartment container cap 100 shown in FIG. 14 further comprises a removable freshness seal 360 applied over the distal opening. In one embodiment, the removable freshness seal is a foil wrapper which restricts or prevents air from passing into the distal compartment. Non-limiting examples of foil wrappers are commonly used in tennis ball containers and food containers. In one embodiment, the removable freshness seal hermetically seals the interior of the distal compartment from the ambient environment. In yet another embodiment, the lid itself provides a hermetic seal when initially releasably attached to said distal opening of the hollow tubular body. Forming a hermetic seal between the lid and the distal opening can be achieved by selecting a one or more attachment members 455 which are adapted to fit with one or more receiving members 355 from said distal compartment to form a hermetic seal. A non-limiting example of a suitable attachment member and receiving member systems is described in U.S. Pat. No. 5,511,680 to Kinne. This tamper evident system allows a consumer to know if the distal compartment had been accessed prior to purchase.

FIG. 15 illustrates a roll of substrates 510 which can be placed within the distal compartment for use in a multi-compartment container cap in accordance with the present invention. The free end 511 of the roll of substrates can be drawn through the one or more minor distal openings provided in accordance with the present invention. In addition, the roll of substrates can be used with any of the embodiments of the multi-compartment container cap shown in the figures provided, where the free end of the roll of substrates can be pulled either through the distal opening when the lid is removed, or through the access area of a hinged flip top lid. The roll of substrates 510 can be one continuous roll of substrates wherein a plurality of lines of weakness 517 is introduced. Examples of lines of weakness include tear lines, score lines or mini apertures along a portion of the substrate. Examples of these types of rolls of substrates with line of weakness are toilet paper and hand towels.

Non-limiting examples of suitable substrates which can be used in accordance with the present invention include thermoplastic films; fibrous substrates including woven and non-woven substrates; paper products including: tissues, hand towels; water-soluble and non-water soluble substrates; and so forth. Those of skill in the art will recognize that the substrate can be a carrier for cleaning, freshening, or fabric softening benefits, such as a dryer sheet or moist cleaning towellete. Non-limiting examples of suitable substrates for use herein are described in: U.S. Patent Publ. No. 2008/0014393 A1 to Denome et al.; U.S. Pat. No. 5,173,200 to Kellett et al., U.S. Pat. No. 5,425,887 to Lam et al., U.S. Pat. No. 5,593,508 to Gatt et al., U.S. Pat. No. 6,025,321 to Smith et al., and U.S. Pat. No. 6,716,805 to Sherry et al.
